The use of a 2D golden-angle spiral trajectory is demonstrated for the measurement of CSF flow at the cerebral aqueduct and foramen magnum. The results compare favorably with a standard cardiac-gated Cartesian scan when retrospectively binned using the cardiac waveform. The spiral data also show variation in the CSF flow waveforms across the respiratory cycle and can be reconstructed as a time-resolved image series for spectral analysis of the flow dynamics.
